ROLQLERSKATE.

SPECIFICATION forming part of Letters Patent No. 299,682, dated June 3, 1884.

Application iled April 1T, 1884. (No model.)

.To all whom', it Vmay concern- Be it known that I, LUOrUs LORENZO RYER- SON, of Boston, in the county of Suffolk and State of Massachusetts, have invented certain Improvements in Roller-Skates, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, making part of this specification, in which- Figure lis a vertical longitudinal section through the center of a roller-skate constructed in accordance with my invention. Fig. 2 is a plan of the under side of said skate. Fig. 3

` is a section on the line x x of Fig. l; Fig. 4, a

section on the line y y of Fig. 2; Fig. 5, a perspective view of the under side of a foot-sup port provided with ways, within which may be slid the bearing of one of the axles. Fig. 6 is a transverse section through the same.

One of the features of my present invention relates to an improved construction of the strengthening-rib secured to and extending under the foot-support of a roller-skate, saidV feature consisting of a solid rib secured to thev under side of the heel-plate, and turned up at its rear to ser-ve as a heel-stop, and to which the heel-strap is secured, the rib being so formed that the portion thereof extending under the heel is located in a plane below the portion of the same extending under the adjustable sole-plate, the middle or connecting portion ofthe rib upon which the shank rests serving as a support for the instep, the employment of said rib strengthening and re-enforcing the foot-support and preventing the bending of the same incident to that class of skates not so provided, while the adj ustability of the parts admits of the skate being adapted for shoes of different lengths.

Another feature of this invention consists, in combination with a goose-neck journal audits bearing, of apair of springs andan arm extending between them, and by which they are actuated, said `arm being secured to the goose-neck and partaking ofthe vibratory or rocking motion imparted thereto by the various changes in the position of the skater while in motion, the springs insuring the gradual yielding of the journals in their bearings as they depart from and return to their normal position.

This invention also consists in a grooved or channeled way formed on the under side of the foot-support, for the reception and to admit of the sliding therein of the bearing of the axle of a pair of rollers, in order thereby to adapt the skate to feet of different lengths.

My invention also consists in a bracket for supporting the springs connected with the yielding goose-neck bearings, in combination with a means of adjusting the tension of said springs; and my invention also consists in a.

clip 7 for securing the rear spring-support ing bracket to the under side of thelongitudinal central rib.

In the said drawings, A represents the heelsupport, B the support for the sole, and C a strong metallic rib, (of the form seen in Figs. l and 4,) securely attached by screws a to the under side of the heel-plate, and extending centrally and longitudinally therewith and across the space between it and the sole-plate and under the latter, the portion b, -corresponding to the shank of the shoe, being located above the planes of the heel and sole plates..

D D are two bearings-one secured to the under side of the heel-support and the other to the under side of the sole-support-both bearings bridging over the central rib, C, and the sole-plate being adapted to slide lon the latter to and from the heel-support, and when adjusted to the length of the foot of the skater being held fast by a pin, c, on a swinging plate, d, entering one of a series of holes, e, in the upper side of the rib. The bearings D D are for the reception of the cylindrical journals h of two inclined bent arms or goose-necks, G G, the lower bend, i, of each projecting outside ofv and under the 4lower surface of its bearing, which is provided with a raised lip, k, at each edge, the form ofthe bearing between its edges being concave or rounded outwardly in crosssection, Fig. a. Secured to the inner lower end of each goose-neck is an arm, Z, its upper end being interposed between the outer ends of two springs, H H, vertically located in one of two brackets, I I, one bracket being secured to the under sideof the rear of the sole-plate,

Vand the other bracket secured to the under IOO eaeh puir of springs irre provided with un :id-A justing-Sereu, 11, by which the tension of their outer ends is increased or diminished, by which Construction the goose-neel: j ournuls ure free to gradually yield und vibrate in their hearings ogn/inst the resistance of the springs `when the position ot the Skater is inelined in either direction, thus allowing the axes of hoth puir of rolls also to ineline7 und the heuringsurfaces ot' the rolls to rest .squarely on the 'loor or purement, the intluenee ot the springs on the relis admitting ol" their gradual departure 'from und return to their norinul position. K K are Clamps, ofWell-linown. eonstruetion, for holding the skate upon the solo oi" the foot.

Another forni of my invention u'hieh udinits of the adjustment et' e skate to feet o' dit'- i`erentlengths is shouninFigs. 5 und (i. lnsuid ignres the foot-support A l is represented :is Continuous from toe to heel, und ro\ided on its underside withnpuir of parallel `guides, p, forming` o grooved uur, r, in which the upper end of u, hearing, l), is adapted to he slid.
